Leviton Decora Smart Mini Plug-In Switch 2nd Gen: Matter basics

Leviton D215P Mini Plug-In Switch: Matter basics

The Leviton Decora Smart Wi-Fi Mini Plug-In Switch 2nd Gen, part D215P, is a hub-free Wi-Fi smart plug that controls lamps, electronics, and small appliances. It connects over 2.4 GHz Wi-Fi, and Leviton says Matter connectivity is enabled by a firmware update available in the My Leviton app. The CSA DCL record (vid 4251, pid 4099) certifies it as Matter device type 0x010A on/off plug-in unit, certified 2025-05-20. Because it is a Wi-Fi Matter device, it does not need a Thread border router; it joins your Matter fabric through your Wi-Fi network and a Matter controller such as Apple Home, Google Home, Amazon Alexa, SmartThings, Home Assistant, Homey, or Hubitat.

CSA certification and Matter transport for D215P

The CSA DCL model record for vid 4251 / pid 4099 lists the product name as “Decora Smart Wi-Fi 2nd Gen Mini Plug-In Switch,” part number D215P. MatterCheck decodes this as Matter device type 0x010A on/off plug-in unit. The certificate ID is CSA252ACMAT45566-24, and the certification date is 2025-05-20. Leviton's product pages state that Matter is enabled by a firmware update via the My Leviton app, and the spec sheet says the D215P “Supports Matter – works with all Matter enabled smart devices and Matter certified smart home platforms.” The device connects to 2.4 GHz Wi-Fi (802.11 a/b/g/n per the Home Controls product data) and requires no hub for Leviton's own app control.

What the Matter certification does and does not tell you

The DCL record confirms the D215P is a certified Matter on/off plug-in unit, but it does not list which controller platforms Leviton has tested with the Matter firmware. Leviton's marketing pages say the D215P works with Alexa, Google Assistant, Apple Home, SmartThings, Sonos, and Matter. The spec sheet adds IFTTT and Schlage integration through the My Leviton app. MatterCheck has not yet reviewed a product-specific platform test for this device, so platform behavior below follows the type-level matrix for Matter plug outlets.

D215P platform support at a glance

These are MatterCheck's type-level matrix answers for the plug_outlet device type.

For Amazon Alexa, the “Starts automations” cell is Unknown in MatterCheck's matrix: no official source or dated hands-on report confirms whether a D215P state change can trigger an Alexa routine. Leviton's own pages say the D215P works with Alexa for voice control, but do not specify Alexa routine trigger behavior.

Cross-platform comparison for the D215P

Across the seven platforms in MatterCheck's matrix, the D215P's on/off plug type is expected to pair and be controllable everywhere. The only open question is Alexa routine triggering, which remains Unknown at the type level. Leviton's spec sheet specifically calls out Apple Home setup via Matter: “Add to the Apple Home app using Matter and control with your iOS device, or Siri for voice control. This Matter-certified accessory requires an Apple Home hub such as HomePod or Apple TV running the latest software.” For Google and Alexa, Leviton describes voice control through Hey Google and Amazon Alexa, and the product pages list SmartThings and Sonos as supported integrations. MatterCheck's guide to Matter smart plug support explains how Wi-Fi plugs like this one differ from Thread-based plugs in multi-admin setups.

Setup notes from Leviton's Matter guide and product data

Leviton publishes a separate “Getting Started Guide - Decora Smart | Wi-Fi Mini Plug-In Switch 2nd GEN (Matter) | D215P” in English, Spanish, and French. The product pages also list a HomeKit-specific getting-started guide, so Matter setup steps should come from the Matter guide, not the HomeKit edition. The spec sheet says the D215P is added to Apple Home using Matter and requires an Apple Home hub. The Home Controls product data notes the D215P supports Wi-Fi security WPA, WPA2, or WPA3, plus Bluetooth v5.0. One customer review aggregated by BestViewsReviews said they “had difficulty finding the smart plug on setup and thought it was a dimmer switch,” and another said they “had to download firmware updates and follow specific steps to pair it with Apple Home.”

What reviewers and Leviton report about the D215P

BestViewsReviews aggregated customer feedback for the D215P-2RW and reported 81% positive overall feedback. In that aggregation, 76% liked the switch mechanism, 75% appreciated the smart features, 83% found installation easy, and 76% were satisfied with durability. Some customers reported setup friction: one said the on/off button controls only the top outlet, another struggled to find the smart plug during setup and thought it was a dimmer switch, and one said the plug is not compatible with one-bar Wi-Fi. Leviton's own materials emphasize the mini design, no-hub operation, and the ability to pair with the DAWSC Anywhere Switch Companion for wall-mounted control. MatterCheck's guide to Leviton Matter devices covers how Leviton's Matter firmware updates work across its Decora Smart line.

Leviton D215P verdict: buy or skip

• Buy if you want a no-hub Wi-Fi plug with Matter certification, a compact design that lets two units share one outlet, and Leviton's documented Apple Home, Google, Alexa, SmartThings, and Sonos integrations.
• Buy if you already use My Leviton and want schedules stored on the device, auto-shutoff, Away mode, or wire-free DAWSC companion switches.
• Skip if you need confirmed Alexa routine triggering from the plug's state changes; that cell is Unknown in MatterCheck's matrix.
• Skip if you want a dimming plug; the D215P is on/off only. Leviton's D23LP is the dimmer plug in the same family.
• Skip if you need a Thread device; the D215P is Wi-Fi only and does not act as a Thread border router or Thread node. See Matter Thread vs Wi-Fi for the trade-offs.
